3.3.8. Clamps for connecting TX, PHOTO OP, PHOTO CL and PHOTO OP / CL photocells
If 24V photocells are used, with separate power supply for the transmitter and receiver, then
connect the "+" power supply of the transmitter and receiver to the accessory power 24VDC, and
"-" the transmitter power supply to the TX terminal (OC type), and powering the receiver to ground. If the
photocells have a common power supply for the transmitter and receiver, then connect their power "-" to
the
TX
output. This method of connection will allow you to use the PHOTO-TEST function, which checks
the operation of the photocells before each gate movement and blocks the movement in the event of a
failure. The PHOTO-TEST function significantly increases the level of security. The
PHOTO OP
input is
dedicated to a photocell installed perpendicular to the entrance edge, it protects the area between the
open leaf and an obstacle, e.g. a wall. The
PHOTO CL
input is dedicated to the external photocell (outside
the property) mounted parallel to the entrance edge, the
PHOTO OP / CL
input is dedicated to the internal
photocell (on the property), installed parallel to the entrance edge.
3.3.9. Manual control terminals INPUT STOP and A, B, C
The
NC
type safety button must be connected to the
INPUT STOP
terminals. If the button is not
used, short-circuit the terminals with a wire.
Momentary
NO
type buttons can be connected to
A, B, C
terminals, which will control the drive operation
in accordance with the program settings. Make the settings from the level of the Bluetooth application. All
unused
NO
inputs should be
left unconnected
. The activation of the manual control button consists in its
momentary pressing.
